sysctl dev.cpu.0.freq reports that my CPU is running at 202 or 404MHz generally: timeserver ~ 127# sysctl dev.cpu.0.freq dev.cpu.0.freq: 404 timeserver ~ 128# sysctl dev.cpu.0.freq_levels dev.cpu.0.freq_levels: 1618/-1 1415/-1 1213/-1 1011/-1 809/-1 606/-1 404/-1 202/-1 I notice the only C states are C0 and C1, and that it's generally running in C1: timeserver ~ 136# sysctl dev.cpu.0 dev.cpu.0.%desc: ACPI CPU dev.cpu.0.%driver: cpu dev.cpu.0.%location: handle=\_PR_.CPU0 dev.cpu.0.%pnpinfo: _HID=none _UID=0 dev.cpu.0.%parent: acpi0 dev.cpu.0.freq: 202 dev.cpu.0.freq_levels: 1618/-1 1415/-1 1213/-1 1011/-1 809/-1 606/-1 404/-1 202/-1 dev.cpu.0.cx_supported: C1/0 dev.cpu.0.cx_lowest: C1 dev.cpu.0.cx_usage: 100.00% last 500us lmmon is not particularly helpful for anything on this board, but that could be because I'm using the Generic kernel and /dev/smb0 is not present: timeserver ~ 134# lmmon -i Motherboard Temp Voltages 255C / 491F / 528K Vcore1: +3.984V Vcore2: +3.984V Fan Speeds + 3.3V: +3.984V + 5.0V: +6.654V 1: 0 rpm +12.0V: +15.938V 2: 0 rpm -12.0V: -15.938V 3: 0 rpm - 5.0V: -6.654V Do you have any other suggestions of tools I could use to help answer your question? Perhaps the lack of other C states is causing the excess power consumption (or perhaps your system is more heavily loaded)? I'm assuming for the sake of simplicity that powerd is already enabled (I'm running with powerd_flags="-i 85 -r 60 -p 100")?
